SCREEN FASTENER.

tain new and useful Improvements in Screen Fasteners; and I do hereby declare the fol.- lowing to be a full, clear, and exact description of the invention, such as will en able others skilled in the, art to which it 7 appertains to make and use the .same.

My invention has for its object to provide an improved fastening device for detachably securing screens in working relation to window frames and sash, and is especially well adapted for use in connection with a pivoted or swinging window sash of the kind disclosed in the prior U. S. patent to Frank Reese, 1,343,933, of June 22, 1920; and, to this end, my invention consists of the novel devices and combinations of devices here inafter described and pointed out in the claims.

- The invention is illustrated in the accompanying drawings, wherein like notations refer to like parts throughoutthe several views,

In said drawings, F'g. 1 is a view in frontelevation showing part of a window frame, part of a window sash assumed to be of the kind disclosed in said prior Patent 1,343,933, and a screen mounted by means of my improved fastener to protect the opening in the window frame. which would be Otherwise unguarded when the sash is swung into its open position, some portions being broken away; 7

Fig. 2 is a horizontal cross section on the irregular line 2'2,2-2 of Fig. 1 I

Fig. 3. is a perspective view showing one of myfastening clamps detached,.this being my preferred form for fasteningthe sides of the screen to the windowframe, as illustrated in Figs..1 and 2; y

Figs. 4a. and 5 are partial'horizontal sections in the, same plane as Fig. ,2, but illustrating a slightly .modified form of clamp for fastening the sides of the screen to the window frame; I

Fig. 6 is a perspective viewof theform of clamp shown in Figs. 4 and:5 detached;

Fi 7 is a vertical section on the line 77 of Fig. 1, showing the form of clamp which I preferably employ for securing the lower end of an upper screen to the central cross Application filed March 2, 1922. .Serial 110.540525.

insane piece or mullion of'a window sash of the a kind disclosed in said prior 1,343,933; and

Fig. 8 is a perspective view of the form of clamp shown in Fig. 7 detached Directing attention first to Figs. 1, 2, 4 and 5, the numerals9 and 10 represent metallic elements making up the side walls of a metallic windowframe or casing, when secured together in properrelation to each patent to Reese,

other. The top and bottom'cross pieces or caps andsills of the window frame are composed of metal and may be of any suitable structure for I ego-operation with the side .walls of thewindow frame. vThe element 9 is of channel form, with its back flange longer than its front flange, and its front flange slightly bent to afford outer faces sl ghtly inclined in respect to each other;

and the element10is ofangular form in.

cross section and is setwith its main vertical flange, abutting the back flange of the 'ele-' ment 9, and theinner member of its cross flange or ribs abutting oneof the inclined outer surfaces of the face flange of the element 9, being inclined to the same slope.

This relation of said parts 9 and 10 leaves three points of the angle bar 10 projecting outward beyond the face flange of theelement 9, as clearly shown'in Figs.2, 1 and 5. The numeral 11 represents a window sash with metallic frame, the pieces of shown in the drawings, this" crossfiange,

being inclined to the same slope as the abuttingsurface of said element 9.

The numeral 12 represents a screen, of the structure disclosed in U. ,S. Patent 1,216,495, granted to the assignee of Frank Reese, February 120, 1917 in which particular form of screen the screen cloth is heldbetween telescoping sections of a two part or sectional frame having projecting marginalflanges. I

The numerals 13represent a pair of angel-- lar guidestrips secured tothe inner mar ginal side flanges of saidtwo-part screen 12;

The numerals 14 audio repre'senhreispectively, a channel and an angle bar rigidly secured together and co-operating to form a side guide and joint'strip. The lateral flanges of the channel bar 14: project toward the sides of the window casing or, frame. which, in all forms thereof, has two portions which stand in angular relation to the body of the clamp and are adapted to be rnade to engag 'and-clampfast to two ofthe pro osition its hook ended oortion 16 enea es 7 l i, a

with theside rib or flange of the angle bar 10 of the frame, and the set screw 1.. en-

' gages behind the frontier facing rib or flange of said angle bar 10, and, when turned in the right direction, becomes operative to secure the needed clamping action between the engaged parts, as is obviousfro n Fig.

2 of the drawing After the said clamp ha beenso applied to the angle bar 10 of the main trame, t he side guises, made up or the parts 14 and'l5, fastened together as before stated, are place'd'in worl'ring; position, and the laterally projecting flange ofthe angl plate 15 will then abut the outer face of the body portion 160]? the clamp and is then secured thereto by a set screw 18.;v The side guides for the sash will then be securely held in their proper working position relative to the'sash and th window frame, and the screen 12 can be moved up and down between the said side guides, if desired; anda limited motion'oii this sort is not onlvdes'irable, but necessary, when my improvement is applied to a window ofthekind shown in said prior patent to Reese, 1,348,933. The window shown in saidpriorpatentis a centrally pivoted single window adapted to fill the entire opening of the window frame, when inits upright or vertical position parallel with the framefbut which assumes an 'ang ular' position, when swung on 'itspivots int'oits open position, The window sash 11,

shown in my drawings, is assumed to-be of thepivoted kind illustrated in said prior patent, and its central cross rib or mulli'on is ofiangular form in cross section, and I connect the-lower end of thescreenlQthereto by the means shown in Fig, 7 er iny' drawing; and, to this end, I provide a oint plate, shownas' made up, of'a sheet ot metal 19 coiled upon itself into a roll ben-d 11 at its I then provide a suitable clamp,

outer edge, which is secured'to the bottom flange of the inner section of the two'part screen 12 by a set screw 20.v The inner portion ofthe sheet=l9 yis bent upward at an angle to th body portion of the sheet, so as to be adented to be seatedbetween the proframe, but differs therefrom in someof its details, as is obvious from the illustration thereof given in Figs 7 and 8. This mullion clamp,;like the other, has abodyportion' 22 and two portions 22 and 22 which stand in angular rel'ationto the body portion 22.

The portion 22* is hook-shaped at its outer end and is adapted to engage over the upper vertical 'iiange of the .mull-ion of the window sash, and the portion 22 is adapted to, be passedthrough the hole 21 in the joint plate 19 and under reach the projecting hori- Zontal flangeloifl the inullion and be made to engage therewith by a *set' screiv'23, working i in a screwthrea'ded seat2 i in that portion oi the clamp, alias is clearly shown in'Tig. 7. When the parts are so connected, the roll or bead 19 of the plate/1 9 will'yieldbr atford slight spring action between the screen 12 and thewindow sash, and, under the oscillation of thefwind'ow sash 11, the screen 12 will receive a limited up anddown motion between itsside guides withinpre determined limits, shown as fixed by stops 25ifO/In16d integralwiththe guide plates [14 and projecting into the spaces between the side flanges of the frame sections of the screen 12, as shown in Fig. 2, and which are adapted to come up. against yoke-shapedlcorner strips, 2-6, shown as applied to theupper corners or the screen 12in Fig; 1 of the drawings.

In Fig. i of the drawings, I show a modi- 'fied forni of side *c1a1np,ffwherein the'body portion ofthe clamp is'split, or,iotherwise stated, wherein the clampiis madeup of two separate sections, eachhaving a 'body portion. 27' carrying one of the clamping. elerne'nts, which stand in angular-relation to their respective body section and bothv of these are shown: as'ofhook shape andiadaptedjto engage, one over the profile rib and'the other over the face ribi'of the angle platelO of the window frame, and then aset screw 28 works through a flange of the angle plate 15 of the side guides to connect the'clarnp and the guides and secure the clamping ac-' tion. V

In Fig. 5 of the drawings, Ishow astru'cture wherein" the parts are "the; same as in' a; with the element 10" of the casing has rib flanges of slightly different shape in cross section, and the side frame of the sash 11 is of a corresponding different shape in cross section. This, however, makes no difference whatsoever in the action of the clamps or other partsof my fastener.

In the instances illustrated, a joint strip is employed with the clamp. strips are of such shape relative to the screen that they prevent the lateral displacement thereof, and the mullion joint strip shown in Fig. 7, takes hold of the lower end of the screen frame and extends to the full width of the screen and the window sash, and thereby helps to support the screen in its proper working position. In

each instance, the joint strip is detachably.

secured to the clamp and the clamp connects the same to a fixed part of the windowframe or casing.

The joint strips may come with the screen and be treated as a part of the screen; and they may, of course, take various forms. For example, when my fastening device is applied to support a screen relative to an ordinary window sash and window frame, wherein the sash is mounted for straight line vertical sliding motion, instead of a pivotal motion, the joint strips may be afforded by an ordinary rectangular skeleton frame in which the screen proper is mounted and the clamps be applied to connect this skeleton frame to the window casing. In other words. the joint strip element may be greatly modified. according to the kind or style of the window and the screen.

The practicability and utility of my improved fastening device has been demonstrated by the successful commercial usage thereof.

It must be obvious that it saves a large amount of time in the mounting and dis mounting of screens, as compared with the old method where the joint strips were The side joint I screwed fast to the window casing. This is especially true where fireproof metallic cas ings and window sash and screens are employed.

What I claim is 2- 1. The combination with a metallic window frame, of a side guide and joint strip extending longitudinally at the side thereof,

and a clamp to which said strip. is secured I detachably engaging the side of the window frame to hold said strip in position.

2. The combination with a metallic win-. dow frame, of an outwardly facing channel member, an angle member rigidly secured.

thereto, both forming a combined side guide. and jolnt strlp extending parallel to the side of said frame, a clamp to which said angle member'is secured detachably engaging the side of said frame.

3. The combination with a metallic window frame having angularly extending flanges, of a guide member and joint strip extending along the side thereof having an outwardly extending vertical flange, a triangular clamp to which said flange is secured engaging said flanges of the frame, and a set screw carried bysaid clamp and engaging one of said flanges of the frame to tighten said clamp and hold the guide member and jointstrip firmly in position.
